Dazu black goat breeding and variety protection method

Abstract

The invention relates to the technical field of goat breeding and variety protection, and discloses a Dazu black goat breeding and variety protection method. The Dazu black goat breeding and variety protection method comprises the following steps of 1) core group building, 2) breeding, 3) inbreeding coefficient control and 4) breeding target. According to the Dazu black goat breeding and variety protection method, excellent individuals are selected in a Dazu black goat production area to establish a core breeding group, so that excellent characteristics such as appearance, body shape, high reproductive performance, meat quality and stress (disease) resistance of big-foot black goats are kept; and through purebred comprehensive breeding generation by generation, consistency of body shape and appearance is improved, growth speed and meat production performance are improved, breeding value and economic value are continuously improved, finally, a Dazu black goat breeding system is furtherperfected under radiation driving of the core group, formation and development of the Dazu black goat breeding industry are promoted, and the purposes of purification, rejuvenation, breeding efficiency improvement and the like are achieved. The method effectively solves the problem that at present, the breeding structure of Dazu black goats is unreasonable.

Description

technical field [0001] The invention relates to the technical field of goat breeding and variety protection, in particular to a method for breeding and variety protection of Dazu black goats. Background technique [0002] Dazu black goats are mainly distributed in 27 towns (streets) in Dazu District, concentrated in Tieshan, Shima and Sanqu towns and other black goat conservation areas, adjacent to Anyue County of Sichuan Province and Rongchang District of Chongqing City Township, pure black coat color, stable genetics; large body size; fast growth and development; high reproductive performance, very prominent multiple births, three births in two years; strong disease resistance, high survival rate of lambs; good meat quality. [0003] At present, the breeding structure of Dazu black goat is unreasonable, the group inbreeding coefficient increases, the breed has not been selected and updated for a long time, and the breed is aging, which cannot promote the formation and deve...
